Topic I: Overview of emotions Why we experience emotions Cognitive explanations: attracted to opposite sex, fear of snakes Physiological explanations: bipolar individuals, on one hand they are incred- ibly happy and then they go into a deep depression. Role of nervous system The Brain The amygdala: relates to hostility, Extreme cases when rage is out of control, amgydalectomy where they take out part of the amygdala to pla- cate the person Prefrontal cortex: thin layer of nuerons that covers the front part of the brain, it is a control mechanism for emotions not a producer of emotions.
